Abstract
The solvation of mono-, di- and trivalent metal ions in liquid ammonia is characterized from molecular simulations using a ‘local’ pKconcept to analyse metal-assisted amide formation.
Highlights
While metal ion solvation in water has been investigated extensively,[1] much less information is available for less common solvents
Ammonothermal syntheses appear interesting for aluminum and gallium nitrides which are semiconductors that are difficult to formulate as large single crystals.[4,6,7]
Liquid ammonia re ects a protic solvent with a pK of 32 and 28, respectively.[8]
Summary
While metal ion solvation in water has been investigated extensively,[1] much less information is available for less common solvents. Liquid ammonia re ects a protic solvent with a pK of 32 (at 1 atm and 239 K) and 28 (at 300 K with xed density to that at 239 K), respectively.[8] Such low tendencies to solvent autoprotolysis may change drastically for molecule coordinating a metal ion.
